20.500.12556/RUL-169433 Sinteza in osnovna analiza Na$_3$V$_2$(PO$_4$)$_2$F$_3$ in Na$_3$V$_2$(PO$_4$)$_3$ kot potencialnih materialov za elektrokatalizo in baterije Na$_3$V$_2$(PO$_4$)$_2$F$_3$ and Na$_3$V$_2$(PO$_4$)$_3$ as potential materials for electrocatalysis and batteries V tem diplomskem delu je prikazan vpliv različnih mas vhodnih spojin na končno razmerje sestavin Na$_3$V$_2$(PO$_4$)$_2$F$_3$ in Na$_3$V$_2$(PO$_4$)$_3$ in njuno čistoto, ter preprečevanje nastajanja neželenih primesi. Za sintezo Na$_3$V$_2$(PO$_4$)$_2$F$_3$ smo uporabili NH$_4$F, C$_6$H$_8$O$_7$, V$_2$O$_5$, 28% razredčeno raztopino NH$_3$, NaF, S1-H$_3$PO$_4$ in NH$_4$F, medtem ko pri sintezi Na$_3$V$_2$(PO$_4$)$_3$ nismo uporabili NH$_4$F. Po kalciniranju smo vzorce analizirali z vrstičnim elektronskim mikroskopom in rentgensko praškovno analizo za preverjanje sestave in homogenosti materiala. Rezultati so pokazali, da s- prilagajanjem parametrov sinteze materiala in metode kalciniranja lahko sintetiziramo ustrezen material za nadaljnjo testiranje z visoko čistoto in dobro kristaliničnostjo materiala, kot potencialni material za natrijeve-ionske baterije. This thesis presents the influencd of diffrent input compounds masses on the final composition ratio of the materials Na$_3$V$_2$(PO$_4$)$_2$F$_3$ and Na$_3$V$_2$(PO$_4$)$_3$, their purity, and the prevention of unwanted umpurities. For the synthesis of Na$_3$V$_2$(PO$_4$)$_2$F$_3$, we used NH$_4$F, C$_6$H$_8$O$_7$, V$_2$O$_5$, 28% ammonia solution, NaF, S1-H$_3$PO$_4$ and NH$_4$F, while the NH$_4$F was not used in the synthesis of Na$_3$V$_2$(PO$_4$)$_3$. After calcination, the samples were analyzed using a scanning electron microscope and x-ray powder diffraction to examine the composition and homogeneity of the material. The results showed that by adjusting the synthesis patameters and calcination method, it is possible to synthesize a sutible material for further testing, with high purity and good crystallinity, as a potential material for sodium-ion batteries.
